Camden, inner borough (1991 pop. 170,500) of Greater London, SE England. Within the borough, residential Hampstead is popular with writers and artists. John Keats, John Constable, George Du Maurier, H. G. Wells, Kate Greenaway, and Karl Marx lived there. It is also known as a piano-making center. Highgate Cemetery in Hampstead contains the graves of George Eliot, Michael Faraday, Herbert Spencer, Christina Rossetti, and Marx. Hampstead Heath, the ancient urban park, hilly, with woodlands, meadows, and ponds, lies mainly in Camden and offers spectacular views of the city. Holborn is the site of part of Bloomsbury, another artists and writers area. Within Holborn also is the British Museum, the Univ. of London, Gray's Inn and Lincoln's Inn (see Inns of Court), law courts, the Royal College of Surgeons, and Hatton Garden, known for its trade in diamonds, gold, and silver. Benjamin Disraeli was born in Holborn, which is also the site of the Post Office Tower, one of London's tallest buildings. St. Pancras has three famous railroad stations: Euston, King's Cross, and St. Pancras.

Camden, city (1990 pop. 87,492), seat of Camden co., W N.J., a port on the Delaware River opposite Philadelphia, settled 1681, inc. 1828. The opening of the Camden and Amboy RR to New York in 1834 spurred the city's growth as a commercial, shipbuilding, and manufacturing center. In 1858, Richard Esterbrook opened a steel-pen factory. The Campbell canned-foods company began here in 1869, and electronics, steel, oil, and chemicals were important in the 20th cent. By the 1960s, however, weakened industries were closing or departing, and Camden was gradually left with pollution, high unemployment, and urban decay, leading to widespread poverty and crime; government corruption was also a problem in the late 20th cent. Walt Whitman's home, the New Jersey State Aquarium (1992), and the battleship New Jersey draw visitors. The Walt Whitman (1957) and Benjamin Franklin (1926) bridges connect Camden and Philadelphia. The city has a branch of Rutgers Univ.
